The parliament has changed its venue several times. Its first site was Ananta Samakhom Throne Hall, used from 1933 until 1974. It then moved to the Parliament House of Thailand, but the building was soon outgrown. In 2008, three sites were considered for a new building. They were the Dusit District, the Mueang Nonthaburi District, and the Khlong Toei District. The Dusit District was chosen by the Samak Sundaravej government.
Name
There are slightly different interpretations of the building's name: The title of the winning design was Sappaya Sapha Sathan. The architects who submitted it said that the Buddhist term sappaya means "comfortable in dharma", and the title is supposed to mean "a place for doing good deeds or good karma". The building's design was inspired by a classic Thai Buddhist tale, Trai Bhum Phra Ruang, and was made to look like a temple as a reminder to officials of "Thainess" and morality, making it truly a Sappaya Sapasathan, "peaceful parliament". Sappaya-Sapasathan is a word combination with sappaya or the seven of Sappaya, meaning "comfortable", "conducive conditions", "supportive", and the "right thing"; and the wordsapasathan, meaning "council of the peaceful".
Design
The Sappaya-Sapasathan design by a team led by Theerapol Niyom was the winner in a new parliament buildingdesign competition. Built to provide more than 424,000 m2 of floor space, at a budget of approximately 12 billion baht, it can accommodate more than 5,000 people and parking for 2,000 cars. Its main features are a Thai pagoda in the center of the building, Suriyan Hall for House of Representative, Chantra Hall for Senate, and the use of 5,018 teak trees as they represent the "DNA of Thailand". It also houses museums, a convention center, a seminar room, a banquet hall, and offices. The design has been criticised for being "religious architecture", embracing "elements of Buddhist and Hindu cosmology".
Construction
The new parliament building, after significant delays, is due to be inaugurated in late 2020. It was contracted for in 2013 and was scheduled to be opened in 2015. It sits on a bank of the Chao Phraya River in Kiakkai neighbourhood of the Thanon Nakhon Chai Si Subdistrict, occupying 300,000 m2 of land. The site of the current parliament building was returned to its owner, the Bureau of the Royal Household, at the end of 2018. Construction of the new building has been delayed for four years. The project budget has ballooned from 14 billion baht to 23 billion baht. Parliament has levied no penalties on the developer for missing the deadline. As the land where the old parliament building sits was already returned to the Crown Property Bureau, Parliament met in an auditorium rented from telecom firm TOT at a cost of 11 million baht per month from May 2019. Since August 2019, Parliament now meets in Sappaya-Sapasathan, although parts of the building remain unfinished.
